Tolong Kaka,Abang aku lagi butuh jawaban nya sekarang pliss banget​

Jawaban:

4x + 3y ≤ 12

4x + 3y = 12

4x + 0 = 12

4x = 12

x = 12/4

x = 3 (3, 0)

4x + 3y ≤ 12

4x + 3y = 12

0 + 3y = 12

3y = 12

y = 12/3

y = 4 (0, 4)

3x + 5y ≤ 15

3x + 5y = 15

3x + 0 = 15

3x = 15

x = 15/3

x = 5 (5, 0)

3x + 5y ≤ 15

3x + 5y = 15

0 + 5y = 15

5y = 15

y = 15/5

y = 3 (0, 3)
